Filed May 31, 1955 BOARD FOR CLAMPING AND EXHIBITING SHEET LIKE ARTICLES Patented Oct. 6, 1936 UNITED STATES BOARD FOR CLAMPING AND EXHIBITING SHEET-LIKE ARTICLES Hans Coray, Zurich, Switzerland Application May 31, 1935, Serial No. 24,320 In Switzerland May 31, 1934 Claims. (Cl. 40-156) This invention relates to a board for clamping and exhibiting sheet-like articles, such as photographs, drawings, printed and written sheets, maps, advertisements, documents, cloth and lace 5 samples, paper patterns etc., which board enables the articles to be quickly clamped and removed Without use of paste or drawing pins, so that the articles are well displaced and at the same time protected from dirt.

The board according to the invention consists of a rear plate and of a pane of glass, flat articles being clamped between the rear plate and the glass pane, edge bars being removably held on at least two edges of the rear plate to press the l5 glass pan against the rear plate.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in whichz- Fig. l shows the board in front elevation.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a top plan view of Fig. 1.

A plywood plate l forming the rear plate of the board carries headed bolts 2 in its upper edge and headed bolts 3 on its rear side near its lower edge. An edge bar 4 of angular cross-section is removably held on the upper edge of the rear plate I by the bolts 2 which engage in slotted holes 5 in the bar 4. If the bar 4 is pushed to the side until the heads of the bolts 2 register with the widened portion of the slotted holes.5, the bar 4 can be removed. An edge bar 6 of U- shaped cross-section is removably secured on the lower edge of the rear plate I by the bolts 3 engaging in bayonet slots 'I in the bar 6. By the shifting of the bar 6 in lateral direction, the open ends of the slots are brought opposite the bolts 3 so that the bar can be slipped oil' the bolts. A pane of glass 8 is pressed against the wooden plate I by the portions of the bars 1I and 6 projecting over the front side of this wooden plate. To obtain a good bearing' of the glass pane 8 against the rear plate I, a soft covering 9, for example of paper, felt paper or plush, is mounted on the front side of the rear plate I and serves as background for the sheet-like articles. These articles, for example photographs, are placed on this covering 9 and then the glass piece 8 is clamped thereover by means of the bars 4 and 6. Suspension eyes It are mounted on the rear side edge bars 4 and 6 may be made of non-corrosive and also at the lower edge of the rear plate I, may

of the rear plate at the upper edge thereof. The

be mounted in the edges thereof, and edge bars of angular cross-section with slotted holes employed at both places. Moreover, edge bars of U-shaped cross-section with bayonet slots may likewise be employed at the upper and lower edges of the rear plate I, in which case the bolts must be mounted on the back of the rear plate near the upper and lower edges thereof. The bars may be of any color and the rear plate may be of plywood, wood, cardboard or other articial pressed substance.

When an edge bar of U-shaped cross-section is employed on the upper edge of the rear plate two apertures must be provided in the rear portion of the edge bar bearing against the rear plate to allow the passage of the two suspension eyes.
